linux_mtd: Bail out early if sysfs node doesn't exist

This checks that the MTD sysfs node we will use actually exists prior
to calling setup code. Although the setup code will eventually catch
such an error, we need to think about the use case before printing a
possibly irrelevant/confusing error message to the terminal.

This patch makes it so that we only print an error message if the
user specifies a non-existent MTD device. Otherwise, the failure is
considered benign and we only print a debug message prior to bailing
out.
